    Using ManagedJbpmContext in TreeNode impls of rich:tree

    Farshid Zaker Newbie

      In my seam application, I have a rich:tree and some TreeNode implementations:
      jsf code:

      <rich:tree id="allTasksTree" switchType="ajax" style="width:300px"
       value="#{tasksRootNode}" var="item" nodeFace="#{item.class.name}">
       <rich:treeNode type="org.jbpm.graph.def.ProcessDefinition">
       <h:outputText value="#{item.name}" />
       </rich:treeNode>
       <rich:treeNode type="org.jbpm.taskmgmt.def.Task">
       <h:outputText value="#{item.name}" />
       </rich:treeNode>
       <rich:treeNode type="org.jbpm.taskmgmt.exe.TaskInstance">
       <h:outputText value="#{item.toString}" />
       </rich:treeNode>
      </rich:tree>
      


      TasksRootNode:
      @Stateful
      @Name("tasksRootNode")
      public class TasksRootNode implements TreeNode {
       private void InitProcessNodesMap() {
       GraphSession graphSession = ManagedJbpmContext.instance().getGraphSession();
       ...
       }
      
      ...
      }
      


      TaskNode:
      @Stateful
      public class TaskNode implements TreeNode {
      ...
       private void InitTaskInstanceNodesMap() {
       GraphSession graphSession = ManagedJbpmContext.instance().getGraphSession();
       ...
       }
      
      ...
      }
      


      The call to ManagedJbpmContext in RootTasksNode class is run perfectly with no problem.
      But execution of TaskNode.InitTaskInstanceNodesMap raises the following (Adding @Transactional or @Interceptors(...) to TaskNode did not help).
      Any idea? I doubt if having TreeNode implementations as SFSB is a good solution. Any idea?
